Abstract

The invention discloses a wear resistant high-strength corrugated board and a preparation method thereof. The corrugated board is formed by compounding upper-faced paper, a V-shaped corrugated core and lower-faced paper, the V-shaped corrugated core is composed of a corrugated core base layer and protective layers sizing on both sides of the base layer, the corrugated core base layer is prepared from the following raw materials in parts: 100 parts of red pine wood pulp, 30-50 parts of bamboo pulp, 20-30 parts of fluff pulp, 40-60 parts of waste paper pulp, 1-5 parts of cyclodextrin, 10-15 parts of oxidated cassava starch, 4-8 parts of composite reinforced fibers, 1-3 parts of cationic polyacrylamide, 0.01-0.1 part of sodium sorbate, 0.1-0.3 part of antimonous oxide, 0.1-0.5 part of poval,5-7 parts of polydimethylsiloxane, and each protective layer is prepared from the following components in percentage by weight: 40-60% of a hydroxylation graphene modified ylate emulsion, 5-10% of sodium caseinate, 20-30% of cationic rosin size and 15-20% of montmorillonite. The corrugated board has the high mechanical strength, excellent wear resistance, excellent shock resistance, excellent water resistance and excellent moisture resistance, has certain antibacterial and mildew-proof effects, the preparation technology is simple, operation is convenient and fast, and repeat sizing is not needed.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, and in particular relates to a wear-resistant high-strength corrugated cardboard and a preparation method thereof. Background technique [0002] Corrugated cardboard is a multi-layer adhesive body, which consists of at least one layer of corrugated corrugated core paper and one layer of cardboard. It has good elasticity and extensibility, and can withstand collisions and falls during handling. It is mainly used for Outer packaging of fruits and vegetables, home appliances, and fragile goods. In the prior art, corrugated paper is mainly made of fiber raw materials. When used in a high-humidity environment for a long time, it is easy to absorb moisture and absorb moisture, resulting in a significant reduction in the mechanical strength and shock resistance of the paper. By coating the surface of the corrugated paper with a waterproof coating It can improve its waterproof and moisture r...
